Abstract

The proposal is for a flexible seal between two housing sections, preferably for an electrical device and a process for its production. The sealing compound (3) is applied to at least one predetermined sealing surface (2) between the housing sections (1) and compressed between the housing sections (1) when they are put together. The sealing compound (3) consists of butyl rubber, preferably with mineral fillers, which is heated before application to the sealing surface (2). In the process for producing the flexible seal, the sealing compound (3) is conveyed by means of a piston pump and a downstream gear pump to a heated application nozzle, and, after the sealing compound (3) has cooled, the housing sections (1) are pressed together and the sealing compound undergoes plastic deformation. (Fig. 1)

Description

Flexible Dichtung und ein Verfahren zu deren HerstellungFlexible seal and a process for its manufacture

Stand der TechnikState of the art

Die Erfindung betrifft eine flexible Dichtung und ein Her¬ stellungsverfahren nach dem Oberbegriff des Häuptanspruchs.The invention relates to a flexible seal and a manufacturing method according to the preamble of the main claim.

Es ist bereits aus der DE-OS 39 37 190 eine Dichtung für ein elektrisches Gerät mit zwei Gehäuseteilen bekannt. Das bekannte elektrische Gerät enthält eine Steuerelektronik für einen automatischen Blockierschutz (ABS/ABSR) eines Bremssystems eines Kraftfahrzeugs und ist im Bereich des Motorraumes angebracht. Das Gehäuse soll nach der Montage des elektrischen Geräts über einen längeren Zeitraum dicht sein und die empfindlichen elektrischen Schaltungselemente in seinem Inneren insbesondere vor Feuchtigkeit und aggres¬ siven Fremdstoffen schützen. Bei einem Kraftfahrzeug können beispielsweise Spritzwasser, Salznebel, Staub oder sonstige am Einbauort der Steuerelektronik vorkommende chemische Agenzien zu schädlichen Auswirkungen führen. Die bekannten Dichtungen sind in der Regel Form- oder Stanzdichtungen aus Elastomeren, die auf die Gehäuseteile aufgebracht werden.It is already known from DE-OS 39 37 190 a seal for an electrical device with two housing parts. The known electrical device contains control electronics for automatic anti-lock protection (ABS / ABSR) of a brake system of a motor vehicle and is mounted in the area of the engine compartment. After the electrical device has been installed, the housing should be sealed for a long period of time and should protect the sensitive electrical circuit elements in its interior in particular from moisture and aggressive foreign substances. In a motor vehicle, for example, splash water, salt spray, dust or other chemicals that occur at the installation location of the control electronics Agents cause harmful effects. The known seals are usually molded or punched seals made of elastomers, which are applied to the housing parts.

Vorteile der ErfindungAdvantages of the invention

Die erfindungsgemäße flexible Dichtung der oben angegebenen Art ist mit den kennzeichnenden Merkmalen des Anspruchs 1 insbesondere dadurch vorteilhaft, daß beim Zusammenfügen der Gehäuseteile die Dichtungsmasse in die Rauhigkeit der Fügefläche eindringen kann und somit zu einer elastischen und sehr dichten Verbindung der Gehäuseteile führt. Gegen¬ über den bekannten Dichtungen aus Elastomeren fallen bei der erfindungsgemäßen Dichtung keinerlei Werkzeugkosten für die Fόrmteile bzw. kein Stanzabfall bei aus Platten ge¬ stanzten Dichtungen an.The flexible seal according to the invention of the type specified above is particularly advantageous with the characterizing features of claim 1 in that when the housing parts are joined together, the sealing compound can penetrate into the roughness of the joining surface and thus leads to an elastic and very tight connection of the housing parts. Compared to the known seals made of elastomers, there are no tool costs for the molded parts or no punching waste in the case of seals stamped from plates.

Im Unterschied zu anderen plastisch auftragbaren Materiali¬ en, wie zum Beispiel Silikon oder Acrylaten, ist bei der erfindungsgemäßen Dichtungsmasse keine Aushärtung notwen¬ dig, da der Butylkautschuk nach dem Auftragen der Dichtung sofort erkaltet. Auch die bei den bekannten Verfahren ent¬ stehenden chemischen Abspaltprodukte, wie Essigsäure, Methanol, Amine oder monomere Acrylate emittieren bei der erfindungsgemäßen Dichtungsmasse nicht, so daß sich insge¬ samt ein umweltfreundlicher Herstellungsprozeß realisieren läßt. Auch die Entsorgung ist umweltfreundlich durchführ¬ bar, da der Butylkautschuk als Kohlenwasserstoff beim Recy¬ cling der Gehäuseteile in der Metallschmelze zu Kohlendi¬ oxid und Wasser verbrennt. Gemäß Unteranspruch 2 wird durch die Zumengung von minera¬ lischen Füllstoffen in vorteilhafter Weise eine Verbesse¬ rung der plastischen Eigenschaften und Verarbeitbarkeit der Dichtmasse herbeigeführt.In contrast to other plastically applicable materials, such as silicone or acrylates, no curing is necessary for the sealant according to the invention, since the butyl rubber cools down immediately after the seal has been applied. Even the chemical cleavage products which arise in the known processes, such as acetic acid, methanol, amines or monomeric acrylates, do not emit in the sealant according to the invention, so that an environmentally friendly production process can be implemented overall. Disposal can also be carried out in an environmentally friendly manner, since the butyl rubber, as hydrocarbon, burns to form carbon dioxide and water in the molten metal when the housing parts are recycled. According to sub-claim 2, the addition of mineral fillers advantageously brings about an improvement in the plastic properties and processability of the sealing compound.

Im Anspruch 3 und den folgenden Unteransprüchen ist ein vorteilhaftes Herstellungsverfahren für die erfindungsgemä¬ ße flexible Dichtung angegeben, das eine einfache Aufbrin¬ gung der erhitzten Dichtmasse aus Butylkautschuk auf die Dichtflächen gewährleistet und nach der in wenigen Sekunden erfolgten Erkaltung der Dichtmasse eine plastische und dichte Verbindung zweier Gehäuseteile ermöglicht.In claim 3 and the following subclaims, an advantageous production method for the flexible seal according to the invention is specified, which ensures simple application of the heated sealing compound made of butyl rubber to the sealing surfaces and, after the sealing compound has cooled in a few seconds, a plastic and tight connection enables two housing parts.

Beschreibung des AusführungsbeispielsDescription of the embodiment

In der Figur 1 ist ein Gehäuseteil 1 als Bestandteil eines Gehäuses für ein elektrisches Gerät gezeigt, wobei dieses Gehäuseteil 1 auch ein Bestandteil einer mechanischen An¬ ordnung sein kann, die durch das elektrische Gerät gesteu¬ ert wird. Beispielsweise kann das Gehäuse eine Motorsteue¬ relektronik beinhalten, die am Motorblock eines Kraftfahr¬ zeuges montiert wird. An einer Dichtfläche 2, die mit einem zweiten, hier nicht dargestellten Gehäuseteil, verbindbar ist, befindet sich eine Dichtmasse 3 aus Butylkautschuk.1 shows a housing part 1 as part of a housing for an electrical device, this Housing part 1 can also be a component of a mechanical arrangement that is controlled by the electrical device. For example, the housing can contain engine control electronics that are mounted on the engine block of a motor vehicle. A sealing compound 3 made of butyl rubber is located on a sealing surface 2, which can be connected to a second housing part, not shown here.

Die Dichtmasse 3 aus Butylkautschuk mit einem Zusatz von mineralischen Füllstoffen ist hierbei durch eine beheizbare Auftragsdüse von einer Kolbenpumpe und einer nachgeschalte¬ ten Zahnradpumpe auf die Dichtfläche 2 aufgetragen worden. Die Kolbenpumpe, die Zahnradpumpe und die Auftragsdüse sind Bestandteil einer herkömmlichen bahngesteuerten Fertigungs¬ anlage, die hier nicht dargestellt ist. Mit der freipro¬ grammierbaren Bahnsteuerung lassen sich auch komplizierte, beispielsweise verwinkelte Dichtflächen nicht nur zweidi- mensional, sondern auch in der dritten Dimension versorgen. Die Dichtmasse erkaltet hierbei in wenigen Sekunden nach dem Auftragen, so daß die Gehäuseteile unmittelbar danach aneinandergefügt werden können, wobei die Dichtmasse 3 auch dann noch ein plastisches Verhalten aufweist. In Figur 2 ist ein Schnitt durch die Dichtmasse 3 kurz nach dem Auf¬ tragen auf die Dichtfläche 2 dargestellt. The sealing compound 3 made of butyl rubber with an addition of mineral fillers has been applied to the sealing surface 2 by a piston pump and a downstream gear pump through a heatable application nozzle. The piston pump, the gear pump and the application nozzle are part of a conventional path-controlled production system, which is not shown here. With the freely programmable path control, even complicated, for example angled sealing surfaces can be supplied not only in two dimensions, but also in the third dimension. The sealing compound cools down in a few seconds after application, so that the housing parts can be joined together immediately thereafter, the sealing compound 3 then also having a plastic behavior. FIG. 2 shows a section through the sealing compound 3 shortly after it has been applied to the sealing surface 2.
